SPECIFICATION forming part of Letters Eatent No. 22,490, dated January29,1884.

Application filed April 16, 1883. (No model.)

To aZZ 1072,0112 it may concern;

Be it known that I, WARREN D. HUsE, of

Laconia, count-y of Belknap, State of New.

Hampshire, have invented an Improvement in KnittingMachines, of whichthe following description, in connection with the accompanying drawings,is a specificatiom'like letters on the drawings representing like parts.

This invention is an improvement on United States Patent N 0. 239,168,granted to me March 22, 1881, and has for its'object to increase thecapacity of the said machine, both as to the amount of work and, thevariety of color in the fabric, and consequently of patterns, which maybe produced thereon. In the machine described in the patent referred totwo yarns of different colors were employed, and when it was desired tochange from one to the other ative position, and its thread wasautomati-.

cally broken off. In the patented machine referred to the pattern-chaincould not be moved for morethan one step at one revolution of thecam-cylinder which. actuates the needles, and the cam-cylinder had butone set of knit; ting-cams, so that but one change of color could bemade at any one rotation of the camcylinder. of the machine as to colorsof yarn introduced and varieties of pattern which could be produced. Toincrease theefficiency of the said patented machine, I have provided thecamcylinder, and also the usual cam-plate for the dial-needles, with twosets of knitting-cams; and I have also provided the machine with twosets of yarn-guides, each composed of at least twoyarn-guides; and-Ihave also provided mechanism for operating both or either. of theseyarn-guides during each rotation of the cam-cylinder; and I have alsoarranged. the gearing by which the pattern-chain is operated so that thesaid'pattern-chain is or may be turned twice during each revolution ofthe cam-cylinder, thus enabling eitherone of four yarns in the fouryarn-guides to be thrown into or out from action during any one courseof knitting;

Such construction limited thescope chine when the yarn-guides are as inFig. 6;

Fig. 10, a similar view, with the yarn-guides as in Fig.8; Fig. 11,adeveloped interiorview of the cam-cylinder; and Fig. 12,asimilar viewof the dial-plate for moving the dial-needles, the said two figures lastreferred to being on a smaller scale.

The dial-plate A, dial-needles a, needle-cyl- 7o inder B,cylinder-needles b, cam-cylinder O, yarn-guides D E, swinging arms G'H,pivot c, levers I J, pit ot d, studs or pins e,yarnchanging pattern K,having camsf and teeth i, pivot g, springs h, rod L, machine-frame M, 75' lever N, pivot Stud k, disk 0, ratchet-wheel Q, pattern-chain P,links Z, projections m a,- screw p, bevel-wheel R, eccentric V,counterweighted lever W, pawl q, spring 1', catch-1e ver X, pivot s, cam10, and yoke z are the same in construction and operation as in mypatentreferred to, except as hereinafter pointed out, and the said devices aredesignated by like letters.

The cam-cylinder, provided with gear-teeth a at its lower end, (see Fig.2,) is engaged by a bevel-gear, B on the shaft B provided with loose andfast pulleys B B the said shaft being extended through a part, M of theframe',l\I.- In this my present invention the 0 cam-cylinder 0 (showndeveloped in Fig. 11) has two sets ofknitting-cams, (1?, of usualconstruction, at nearly opposite points, to operate the needles b twiceduring each revolution of the cam-cylinder, and at its outer side the 5said cylinder carries two extra pairs of yarnguides, D E, like thosemarked D E, and cooperating with the same are arms G H, actuating-levers I J, pattern K i f, and a lever, X a, springs r h, the sameas those at the opposite side of the cam-cylinder O, and marked withlike letters without, the prime. The

cam-plate C (see Fig. 12) has also two sets of knitting-cams, Zr, eachto operate the needles a twice during each revolution of the can plate,thus enabling two courses to be knitted at each revolution of thecam-cylinder and cam-plate, and also enable either or both of theyarn-guides of each set to deliver the yarn carried by it to the needlesfor the whole or part of each knitted course. The teeth a of thecam-cylinder engage the teeth of the bevelgear R common to my saidpatent; but the latter gear has a gear, I)", connected with it, whichengages the gear I), with which is attached the eccentric Y. These gearsb b are, however, of such size with relation to the gear R and theratchet Q that the latter is moved for the space of two of its teethduring each revolution of the cam-cylinder, so that the saidratchet'wheel and pattern-chain P, the links Z of which are supposed tobe of a length suiticient to control the color of the yarn used for foursuccessive courses, is movedsufliciently far at each stroke of the pawlq to carry a link, 7, completely under and past the pin it of the leverN. The links have projections 21, of various widths and located atdifferent points thereon, in order to determine which pair or set ofthread-guides is to be operated during acertain revolution of thecanrcylinder, or whether both of the said sets are to be operated ateach revolution of the said cam-cylinder in successive or alternatecourses, a narrow projection, n, holding the rod L up only while theratehet-wl1eel Q is moved one step, whereas a broader projection, as atof, will hold the said rod L up while the said ratchetwheel is moved twosteps or more, according to how much of the length of each link isoccupied by a projection to hold up the lever N. In the patent referredto the ratchet-wheel is moved but for one step during each rotation ofthe cam cylinder, and but one color could enabled to produce fourcourses of knitting during any two revolutions of the cam-cylinder, andthe said four courses may all be produced with yarns of differentcolors, and either color may appear in either course, that beingdetermined by the location of the projection on the links Z of thepattern-chain.

The bobbins for yarn, two only of which are shown, are supported on aplate e", and usual tension devices (not shown) for the said yarns willbe carried by the rod 0.

The bed for the dial-needles is marked f*.

I claim The eanrcylinder having two sets of knitting-cams, thecylinder-needles, needle-bed, the bed or plate for the dial-needles, thecamplate, the dial-needles, and two sets of knitting-cams on thecant-plate, and two sets of yarn-guides composed each of two separateyarn-guides, combined with two yarn-changing patterns, a pattern-chain,and'means actuated thereby to permit the two yarn-changing patterns tobe moved at each revolution of the cam-cylinder, and with means torotate the said cam-cylinder and to move the pattern chain two steps ateach revolution of the camcylinder, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing wit nesses.
